Description

Technical Field

[0001] The utility model relates to the technical field of luggage box brackets, in particular to an electric support rod fixing structure, a car luggage box cover and a car. Background Art

[0002] The existing electric trunk lid of a car realizes the electric opening and closing of the trunk lid by extending and retracting an electric strut.

[0003] There are ball sockets on both sides of the electric strut, one of which is clamped on the ball stud of the body side sheet metal, and the other side is clamped on the ball stud on the hinge side; the ball stud on the body side is screwed on the body, and the ball stud on the hinge side is generally riveted or welded to the hinge; when assembling, the ball socket on the hinge side is clamped first, and then the ball socket on the body side; when the vehicle wiring harness or electric strut fails and the wiring harness or electric strut needs to be disassembled and replaced, due to the limitation of operating space, it is extremely difficult or impossible to disassemble the ball socket on the hinge side, and it can only be destroyed and disassembled, which takes a long time for maintenance and has high maintenance costs. Utility Model Content

[0004] To solve the above problems, the utility model provides an electric strut fixing structure, a car trunk lid and a car, which solves the problem of inconvenience in removing the hinge-side electric strut in the narrow space of the trunk lid when the vehicle wiring harness or the electric strut fails.

[0005] The utility model provides an electric support rod fixing structure, comprising a hollow hinge, a ball bolt, a ball bolt fastening sleeve device and a fastening nut;

[0006] The ball stud fastening sleeve device is embedded and sleeved in the through hole of the hinge to prevent the ball stud and the fastening nut from being excessively screwed together and causing the hinge arm to be concave and deformed. One end of the ball stud is inserted into the ball stud fastening sleeve device, and the end of the ball stud is exposed outside the through hole on one side of the hinge and is screwed and fixed with the fastening nut. The ball stud is directly screwed on the hinge through the ball stud fastening sleeve device and the fastening nut, so that the electric strut clamped with the ball stud on the hinge side can be easily disassembled in the narrow space of the trunk lid without breaking it, thus saving disassembly time and disassembly cost. When only the electric strut needs to be disassembled, first use a tool to separate the ball stud on the body side and the ball socket of the electric strut, and then loosen the ball stud on the hinge side.

[0007] The ball bolt fastening sleeve device is a tubular cavity as a whole, and a plurality of riveting protrusions are evenly arranged on the circumferential outer wall of one end of the tubular cavity. The side walls of the hinge object are respectively provided with a first through hole and a second through hole. The riveting protrusion on one side of the tubular cavity is interference fit with the inner wall of the first through hole to ensure that one end of the ball bolt fastening sleeve device is fastened to the hinge by riveting, so as to prevent the ball bolt fastening sleeve device and the hinge from shaking due to a gap caused by long-term driving bumps. The other side of the tubular cavity is accommodated in the hollow cavity of the hinge, and the end wall on the other side of the tubular cavity is limitedly contacted with the inner wall of the outer edge of the second through hole. The end wall on the other side of the tubular cavity is zero-fit with the inner wall of the hinge, and cooperates with the corresponding outer fastening bolt, so that when the ball bolt and the fastening bolt are tightened to the hinge, the hinge arm on the fastening path does not deform and the torque does not decay.

[0008] Each riveting protrusion is in the shape of an isosceles triangle, so as to facilitate the riveting fixation between the riveting protrusion and the corresponding through hole, and prevent the ball stud fastening sleeve device from shaking on the side of the through hole.

[0009] The end face of one side of the tubular cavity where the riveting protrusion is located protrudes outside the hinge end face where the first through hole is located. The height difference between the end face of one side of the tubular cavity where the riveting protrusion is located and the hinge end face where the first through hole is located is 0.15mm-0.25mm. The height difference is designed so that when the fastening nut is screwed into the ball stud, the fastening nut is first crimped into the end face of one side where the riveting protrusion of the ball stud fastening sleeve device is located. When the fastening nut is screwed into contact with the corresponding outer side wall of the hinge, the inner inner wall of the tubular cavity on the side where the riveting protrusion is located will be deformed and tightly contact the threaded side wall of the ball stud at the corresponding position, thereby further preventing axial and radial shaking of the ball stud.

[0010] The ball stud includes a ball head and a rod portion, the rod portion is a stepped structure with a reduced diameter, including a first rod body and a second threaded rod body, the diameter of the first rod body is larger than the diameter of the second threaded rod body, the connecting surface between the first rod body and the second threaded rod body corresponds to the outer wall of the outer edge of the second through hole, the second threaded rod body is threadedly connected to the second through hole, the connecting surface between the first rod body and the second threaded rod body cooperates with the corresponding end surface of the ball stud fastening sleeve device to fix the corresponding hinge wall to prevent the ball stud on this side from shaking at the second through hole.

[0011] It also includes an electric support rod, both ends of which are respectively provided with ball sockets, and the ball socket at one end of the electric support rod is matched and rotatably clamped on the ball head of the ball head bolt connected to the hinge.

[0012] A car trunk lid comprises a trunk sheet metal and a trunk lid, and also comprises the electric strut fixing structure, wherein two ends of a hinge are rotatably connected to the trunk sheet metal and the trunk lid respectively, a ball socket at the other end of the electric strut is rotatably clamped on a ball stud of the trunk sheet metal, and the electric strut is retractable to drive the trunk lid and the trunk sheet metal to hinge open and close.

[0013] A car comprises a car body and a central controller, and also comprises the car trunk cover, wherein the car trunk cover is arranged at the rear of the car body, and an electric support rod is electrically connected to the central controller through a wire.

[0014] Beneficial Effects

[0015] The utility model solves the problem that when the wiring harness or the electric strut of the whole vehicle fails, it is inconvenient to disassemble the electric strut on the hinge side in the narrow space of the trunk cover. BRIEF DESCRIPTION OF THE DRAWINGS
